NON-CAPSIZABLE BOAT.

To all whom it may concern Be it known that I, Bnnnnann'r A. BECKER, acitizen of the United States, residing atthe city of St. Louis and Stateof Missouri, have invented a certain new and useful Non- GapsizableBoat, of which the following is a clear, full, and exact description,refer ones being had to the accompanying drawing, forming a part of thisspecification.

My invention relates to non-capsizable boats and has for its principalobjects, a series of stationary air chambers running longitudinallyalmost the entire length of the boat, also a secondary air chamber,running almost the entire length of the boat, and arranged to swing onhinges fastened to the gunwale and said air chamber, with a spring stopto regulate the amount of swing. Both sets of air chambers are used onbot-h sides of the boat as illustrated in the accompanying drawing, inwhich- Figure I is a vertical section through the boat, looking towardthe bow. Fig. 11 is a side elevation, shown broken in the middle.

Similar numbers refer to similar parts throughout the several views.

1 represents the gunwale of the boat, 4; the heel, and 8 the rudder.

7 represents the hinged air chambers with hinges 5, spring stop 6, andair space 2. 3 is one of the series of stationary air chambers, runningthe entire length of the boat.

In event that a capsizing action occurs with this boat, it is firstcounteracted by the buoyancy of the stationary air chambers 3. Then ifthe same side of the boat is still further depressed in the water, thecapsiz- Specification of Letters Patent.

iug action is counteracted by the buoyancy of the hinged air chambers 7,which immediately swing out to the limiting position of the spring stop6. This movement of the swinging chambers so increases the radius ofbuoyancy, that it renders the boat practically impossible to capsize.The spring step has a tendency to moderate sudden stop, when theswinging chambers open out. I have shown here one of the several kindsof stops that I could use to advantage. The swinging air chambers mightalso be made with separate compartments so that if one of thecompartments are punctured, it will do but little harm. It might also beof advantage to make the swinging air chambers in halves, so that if theload in the boat was in the rear part, it would only be necessary forthe rear half to swing out, and still perform the desired function. Agreat advantage of this type of chambered boat is the possibility of soarranging these chambers as to conform with the outside line of theboat, and not destroy its beauty. This is clearly shown in Fig. I.

I claim:

In a. noncapsizable boat, the combination of a hinged air chamberarranged to swing on hinges fastened to the gunwales and chamber, with aspring stop, said stop to be fastened to said air chambers and fixingthe limit of the swing of said hinged air chambers.
